Construct the indicated confidence interval for the population mean using the t-distribution. Assume the population is normally

DanielleElmas [232]

Using the t-distribution, it is found that the confidence interval is (14.2, 14.8).

<h3>What is a t-distribution confidence interval?</h3>

The confidence interval is:

$\overline{x} \pm t\frac{s}{\sqrt{n}}$

In which:

$\overline{x}$ is the sample mean.

t is the critical value.

n is the sample size.

s is the standard deviation for the sample.

The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 18 - 1 = 17 df, is t = 2.1098.

The other parameters are given by:

$\overline{x} = 14.5, s = 0.68, n = 18$ .

Hence, the bounds of the interval are given by:

$\overline{x} - t\frac{s}{\sqrt{n}} = 14.5 - 2.1098\frac{0.68}{\sqrt{18}} = 14.2$

$\overline{x} + t\frac{s}{\sqrt{n}} = 14.5 + 2.1098\frac{0.68}{\sqrt{18}} = 14.8$

The confidence interval is (14.2, 14.8).

What is the lower quartile , median, and upper quartile of ... 3 6 3 8 5 2

dimulka [17.4K]

First, order up the numbers into order:

2, 3, 3, 5, 6, 8

Next, cut off the ones on each side to get the median.

2, 3, 3, 5, 6, 8

2, 3, 3, 5, 6, 8

Now with this, add the two middle numbers and divide by 2 to find the avg. of them:

3+5 = 8

8/2 = 4 is the Median

Next, split up the number list into the lower section and the higher section, now knowing the Median:

2, 3, 3 Lower

5, 6, 8 Higher

Then, find the Median of each of these sections.

2, 3, 3 Lower Quartile is 3

5, 6, 8 Higher Quartile is 6

Hope that helps.
